	well, to verify new transactions you only need the UTXO set - problem is, in order to get the UTXO set you have to parse the whole transaction history starting from day zero. 

	you can run a prunning node, which only keeps the UTXO set, but that only saves storage space - you still need to process the whole blockchain at least once. 

	there doesn't seem to be an easy solution to the problem, otherwise it would have been adopted, I'd assume.
